' a citizenof the United States, residing at New York city,`kin the county and State of New York, have invented .certain -new and useful Improvements in SewagefEjectors, of

"which the following, in. connection withthe accompanym drawings and reference chariactersmarke thereon, is a full, clear, and

exactspeciiication, sufficient to enable others to make and use my invention.

y y lh'e object of my present invention is to provlde or produce a sewage ejector, or sewage lift as it is sometimes called, of few and ,f place, whichwill be automatic in action, eilisimple parts, easy to construct and mount in cient, reliable,l durable and vnot liable to .get

out of order.

To accomplish the aforesaid objectand to secure other and. further'advantages in the matters of'constru'ction, operation, applica- .tionand use, my im rovements involve certain new and usef particular features of construction, relative arrangements or ,conibinati'ons of parts and principles of operation, as will be herein first fully described and then pointed out in the claims. l

- In the 1 accom nying drawings forming part of this speci cation I have shown as ew- -age ejector or sewage lift constructed and ar ranged for voperation in accordance with my. invention an involvinthe principles thereof.

In these drawings igure 1 1s a vertical view, artly in section and partly in elevation, s owing the complete apparatus ready for use. Fig. 2 is atop or p an view corre sponding with Fig. 1. Fig. '3 is a horizontal section and planview on planes through line 3-f3 -of Fig. 1v.' Fig. 4 is a view, partly in s ec.- tion and partly in elevation, of' a fragment of the upper part of. the device as shown in Fig.

C, and `it receives sewage at any convenient'point,.asfthrough thel pipe a, and preferably dischargesit throu he() an openin `in the bottom connected with t e, base and eading to `the outlet or discharge pipe b, but the particular arrangement of inlet and-discharge is not material.` A valve casing, D, is `located between the tank and the inlet, and in this is a check valvev of any of the ordinary forms, the axle of which is shown at c, to prevent back-flowwhen pres, sure is applied. A valve casing, E, is also applied between the outlet pipe and the tank, and this is suppliedl with any ordinary formv of check valve, the axle of which is representyed at d, toprevent backflowofthe material which may-be ejected.

. .F is a'pipe for admitting steam or air under. 75

pressure to accomplish the required ejection or lifting of the material.

The design ofthe apparatus is to automat-k ical'ly admit steam `or air under pressure as soon as the tank becomes filled tothe desired 'go hei ht and to crut off this inflow as soon as the tan has been sufficiently emptied of its conw tents.

` G is a float located in the tank and arranged to rise and fall with thematerial 35 therein. .T he arm, d1, of this lfloat within ,the tank vconnects with a suitable arm, e,von the exterior through-a suitable packing casingf, secured against leakage; and the .arm- `e isv connectedwith and arran ed'to movea stern, 9o'

A branch, H2, connects with vthe discharge outlet from the tank and an-v other branch, H3, connects with the pressure lpipe 1 leading to the device foropening or closingthe inlet valve for steam or air under pressure.

lBetweenthe branch and the tube H is a valve, the casing ofwhich is re resented at. 10o h, to close the communlcation etween the' branch H2 and the tube I-I to prevent material from entering and interfering with the loperation of thevalve controlled byfor connected with the `float G, but-to outjlowv of ASavater .through the ranch H2 theiloat (Jl-descends.

Under the construction and arrangement so far shown and described, when the sewage risesin thetank to a sufficient degree, water will enter pipe 1,

assing down through branch 11 and underl iaphragm Z to open t e valve/m and thus automatically admit fluidV under pressure-through tube K to the top of j After the pipe 1 has received one charge of.

As the material descends in the tank the float G descends with it, causing the valve stem g to rise or the valve controlled thereby to open, thus permitting the own to the level of Connected with the ipe 1 and communi- Ifie tank B is a branch lator pipe H1. I'n the branch 14 is a light, balanced valve, represented at o, Ithe purpose of which is to close the passage through the branch 14 asvsoon as pressure is admitted lpli tothe to Iof the tank through the pipe K but whic valve willremain normally .open so that-the contents of the tank above the sewage therein may flow past the valve without c osing it as thesewage rises in the tank.

contents of the ap aratusdischarged and pipel drained, venti ation or relief is secured and the valve o automatically opens. The

Iupper-part or section of the tank is made of smaller diameterthan the lower part so as to 4make the height of the sewage more sensitive to an inflow; that is, so that the inflow will rise more rapidly in the section of small diameter than in thebottom part of larger diameter.

The improved apparatus .willdischarge hot terand isnot efnycondition 'of fected in its operation tanlli independent the matter which enters it to be ejected. The branch L connected with the pipe F and with the ipe K is a by-pass and 1s sup lied with a va ve, as as L1, convenient for a niittinmuid under ressure to the top of the l)y of the automatically acting valve m, in case it be necessary or desirab e-at any time to so admit it. Should the material rise above the strainer protected inlet to pipe 1, water will flow over into this pipe and its weight will be added to the contents of the pipe to influence the movement of the valve m. In` addition `to this a syphonic action will beproduced in the top of the tank through the pressure ipe 1 to remove the water from the top of t e tank.

The arts are arranged to be made easily accessilile for neeessaryattention orrepairs, and the device constructed and arranged for operation inaccordance with the fore oin explanations will be found to answer al the purposes or objects of the invention hereinbeore alluded to. 1 v

It will be observed that the float'G is not employed to directly govern the valve contro ling the steam or air sup ly but isv only utilized to control the relief o which is a comparatively light an duty to perform.
